# MD for: https://www.mercadopago.com.uy/developers/en/docs/qr-code-legacy/integration-configuration/qr-dynamic/introduction.md \# What is the dynamic QR model? It allows the inclusion of the payment value in the QR code. Each QR represents a single order and amount. \*\*Its main characteristic is the one-time payment\*\*, meaning that reusing the QR is not allowed after completing the payment. This model is ideal for collections with QR codes on ticket and desktop services or value-included payments. ## Model description The main characteristics are: - The value is already configured in the QR code. - Allows you to display the QR code on a printed ticket or Point of Sale (POS) device. A fixed QR code at the point of sale is not required. - You can charge several orders simultaneously with different codes. > WARNING > > IMPORTANT > > Remember that you can only use QR for in person payment solutions.
